In the article How LINQ expression is composed LINQ select clause was described. Web developer can change it to get a subset of data. For example, he/she could pull out a list of first name strings like this:
Dim matches = From client In clients _
select client.FirstName
or a list of strings with both first, middle and last names:
Dim matches = From client In clients _
select client.FirstName + “ “ + client.MiddleName + “ “ + client.LastName
Web developer can use standard VB.NET operators on numeric data or strings to modify the information as he/she’s selecting it. This changes the type of collection that’s returned—it’s now an IEnumerable<string> collection of strings, rather than a collection of Client objects.
